Spotted by MobielKopen, the HTML5Test benchmark is for a phone dubbed the SM-G405F, and the resolution is listed as 412 x 869. Now, that’s obviously not the full resolution, and that's because the benchmarks are carried out using only a portion of the screen – as MobielKopen notes, the Galaxy S9 has appeared in the same benchmark with the resolution listed as 412 x 846.

To get the full resolution of the S9 you multiply it by roughly 3.5 times, and doing the same with this new phone gives us a resolution of 1440 x 3040, up from 1440 x 2960 on the Galaxy S9.

So that would make this phone marginally higher-resolution, but more importantly that resolution would equate to a 19:9 aspect ratio, rather than the 18.5:9 aspect ratio on the Galaxy S9. That would mean the Samsung Galaxy S10 – or whatever this is – has a longer screen than the S9.

A bigger screen in the same size body

Now, Samsung could simply make the phone bigger to achieve that, but a more elegant solution would be to slim down the top and bottom bezels, giving the phone a bigger screen in the same size body. A notch is also a possibility, but probably unlikely given that Samsung has so far shied away from notches.

It’s worth taking this with a huge side of salt, especially as the model number doesn’t actually line up with past Galaxy S handsets, but, as SamMobile notes, Samsung has a history of testing its flagships with fake model numbers.

Add to that the fact that this is a new aspect ratio for the company and a seemingly high resolution, and that the phone listed as running Android 9 Pie, and the Samsung Galaxy S10 becomes a likely possibility.
